Wheel Hubs Review

These hubs do not fit as presented. They do not mount to Lite-Flite wheels. If it is a small size Lite-Flight wheel, you might be able to get away with running a long screw down the center but this is not a dependable way to transmit torque from the hub to the wheel. If you are using a larger size Lite-Flight wheel, you will have to perform extensive modifications to mount the hubs properly, and since the Lite-Flite wheels themselves feature flimsy pressed-in plastic hubs, you are likely to not be thrilled with the results. Lastly, these hubs do not fit the shafts of some of the motors that are presented as being compatible with these hubs, and there is not enough material to drill them out and still have enough meat for the set screw to grab. I ended up turning my own hubs. It was the only way to go. Maybe these hubs do work with very specific motor/wheel combinations. The vendor should be more accurate in their representations of the instances where these hubs are a truly applicable.

6mm hubs

The screw down the middle is not the complete torque transfer. The torque is transferred via the hub itself (set screw to the shaft) against the press-fit of the wheel to the hub. If you need a more secure connection, a CA glue or hot glue of the hub against the soft lite flite can help. The screw is simply meant to hold the two sides of the wheel (one side plastic Lite Flite, other side aluminum flange of hub) securely together.

As for the hub being used with some of our motors with 7mm shafts, yes there is sufficient 'meat' left when boring it out from 6mm to 7mm. The wall of the hub after re-boring measures out at 2.85mm, down from 3.35mm, still plenty thick enough to support a shaft and keeping enough threads on the set-screw hole.

Please be sure to read the installation guide when using these with Lite Flite wheels. Half of the plastic hub is meant to be discarded. Do NOT use both halves of the plastic lite flite wheel with this hub, we find that a lot of our customers make this simple mistake. You need to pull the two plastic halves of the Lite Flite wheel apart and throw out one side when using this hub.
